The Second Facial Micro-Expression Grand Challenge (MEGC): Spotting and Recognition

Update: The first place winner will receive an award from our sponsor - Image Metrics Ltd.

Facial micro-expressions (MEs) are involuntary movements of the face that occur spontaneously when a person experiences an emotion but attempts to suppress or repress the facial expression, typically found in a high-stakes environment. As such, the duration of MEs is very short with the general duration of not more than 500 milliseconds (ms), and is the telltale sign that distinguishes them from a normal facial expression. Computational analysis and automation of tasks on micro-expressions is an emerging area in face research, with a strong interest appearing as recent as 2014. Only recently, the availability of a few spontaneously induced facial micro-expression datasets has provided the impetus to advance further from the computational aspect. Particularly comprehensive
are two state-of-the-art FACS coded datasets: the Chinese Academy of Sciences Micro-Expression Database II (CASME II) with 247 MFEs at 200 fps and the Spontaneous Facial Micro-Movement Dataset (SAMM) with 159 MFEs at 200 fps. In addition, there is recent interest in acquiring “in-the-wild” datasets to further introduce real-world scenarios. While much research has been done on these datasets individually, there have been little attempts to introduce a more rigorous and realistic evaluation to work done in this domain.
This is the second edition of this workshop, which aims to promote interactions between researchers and scholars not only from within this niche area of facial micro-expression research, but also including those from broader, general areas of expression and psychology research.

This workshop has three main agendas:

To solicit original works that address a variety of challenges of ME research, but not limited to:
